If Something Goes Wrong
Display problems
A message displays saying that there is a problem with your 
display settings and that the adapter type is incorrect or the 
current settings do not work with your hardware.
Reduce the size of the color palette to one that is supported by the 
computer’s internal display.
To change the display properties:
1
Right-click in a blank area of the Windows
®
 desktop.

The display mode is set to Simultaneous and the external 
display device does not work.
Make sure the external monitor is capable of displaying at 
resolutions of 800 x 600 or higher. Devices that do not support this 
resolution will only work in Internal/External mode, and not 
simultaneous mode.
Small bright dots appear on your TFT display when you turn 
on your computer.
Small bright dots may appear on your screen display when you 
turn on your computer. Your display contains an extremely large 
number of thin-film transistors (TFT) and is manufactured using 
high-precision technology. Any small bright dots that may appear 
on your display are an intrinsic characteristic of the TFT 
manufacturing technology. Over a period of time, and depending on 
the usage of the computer, the brightness of the screen will 
deteriorate. This is also an intrinsic characteristic of the screen 
technology. When the computer is operated on battery power, the 
screen will dim and you may not be able to increase the brightness 
of the screen while on battery power.
